Ozone is an unstable oxygen molecule (O3) that reacts anything it bumps into. Because ozone can react with and break down anything it comes in contact with, it makes this chemical very effective for removing odors and killing mold and mildew. Unfortunately, it could also kill your small animals! In fact, the very thing that makes Ozone so effective at removing odors, also makes it dangerous. If it is present in high enough concentrations to eliminate bad smells, then it is also reacting with your skin, eyes, lungs, and other exposed areas. If you can smell it, then it is reacting with you and causing long term damage. You would not feel comfortable having the smell of gasoline, or glue, present in your home permanently, but Ozone is performing the same type of long term lung and skin damage as these volatile chemicals. It just smells nicer. Why do you sell a device that emits dangerous Ozone?
